This is especially useful on targets that have an off switch instead of a reset button like the gigabeat but also applicable to other targets (power loss due to run down battery etc)

The patch:
- displays the date/time settings screen at start-up on encountering an invalid RTC time
- the screen is pre-set with the build date (instead of 01/01/2000) reducing the number of button presses even more

This might be quite confusing for blind users and pretty much annyoing for users that don't care about their RTC (but lose power frequently like swapping batteries on archos devices). This has also been mentioned in IRC a couple of days ago.
